I'd just like to ask what the F happened here. he attacked a minute or 2 into 2nd Eye, and then this happened.
GFX and it should resolve. This as well as black boxes showing up on your screen are signs you need to GFX or your client is going to crash.
Krexel just like Zak and HT suffers from the same issue - the need to refresh your screen via changing your graphics settings after each "part" is killed. In this case, gfxing after the first eye is killed.
